My invention relates to furnace construction and refers more particularly to a .unit or segmentally supported Wall that is maintained positioned by gravity.

One object of my invention is to provide a framework for a furnace comprised of a series of buckstays, upon which are held a series of brackets adapted to hold firebrick.

Another object of my invention is to provide a furnace wall wherein the firebrick constituting the wall are held positioned by gravit A fiirther object of my invention is to provide a furnace wall whereinthe firebrick constituting the wall are substantially diamond shaped. A still further object of my invention is to provide a unit or segmentally sup orted wa 1 that can be easily repaired from t e out- 99 side of the furnace.

Still another object of my invention is to provide a unit or segmental furnace wall wherein any part of the furnace wall can be easily repaired without interfering with any other portion of the wall.

Another valuable feature ofmy invention resides in the method of construction whereby the back of the wall may be cooled by passing air into the bottom of the space beiotfiveen the buckstays and taking it out at t eto i A fiirther valuable feature of my invention resides in the combination of a series of buckstays holding a single furnace wall on one side by uni ue brackets and hOldlIl fl.

series of detacha 1e doors on the other side.

A still further valuable feature of my invention consists of the particular construc- I tion of a furnace wall'wherein the laborcostis reduced, the furnace construction simplified and the wall may be built up with unskilled labor. A It is obvious that any portion of a wall or a complete wall may be constructed by utilizmg this method of construction. With these and other objects in view, I accomplish these results by the means shown in the accomanying drawings, which illustrate the pre erred embodiment of my invention, wherein similar numerals refer to 'of the blocks with a supporting roove.

Figure 13 is an isometric view of the su port shown in Figure 11. Figure 14 is an isometric view of the block shown in,v Fi re 11.

Figure 15 is an isometric view of another form of support. A

The furnace 1 is comprised of a front wall 2, a bridge wall 3, and side walls, one of which is shown-by 4, boiler tubes 5, baflles 6 and 7, drum 8, outlet to stack 9, ash cleanout opening 10, air box 12 and a burner 13, which may be oil\or pulverized coal. a i

e air may circulate in the front wall throughthe inlet 14, passing upwardly into the manifold15, and-taken therefrom to any desirable place by the pipe 16, and the air in the side walls may enter the wall through the 96 inlets 14a and pass into the manifold 150,

similanto the manifold '15 and the air may be utilized therefrom as desired. I The ructure is comprised of a plurality of Ibeams 11,1 0 which a series of brackets 18 100 are held by the bolts 19 and nuts 20, each in Figures 6 and 10, are used, the'upward bracket supporting courses of bricks 21, said brackets spaced when desired to provide for a filler block 22 therebetween. and on the outside of these buckstays or I. beams 17 is bolted a series of doors 23 by the bolts 24 and nuts 24a, so that when the wall is c6mpleted, the space 25 will provide an air space for circulating air behind said wall.

The block 21, seen in Figs. 1 and 2, and shown in detail in Fig. 4 is provided with a flat seat 26, a recessed part 27, an upwardly sloiring groove 28, a projecting portion 29, an notches and 31, the parts 27 and 29,

15 being at right angles to the surface 26, and

the top .32 and bottom 33, sloped upwardly parallel to the groove 28.

The blocks 34, shown in Figure 5 are each provided with the same fiat seat 26, recessed art'27, upwardly sloping groove 28, a pro ecting part 29, and the notch 35, which engages a corresponding notch 30 of the block 21, and a notch 36 adapted to engage with a notch 31 of the block 21, the top surface 37 and bottom surface 38, being similar to the parts 32 and 33 in block 21.

The block 39, shown in Figure 6, is similar to the block 21, shown in Figure 4, except that the wall 29 is deeper,'the recessed part 27 ehminated, and the slot 28 replaced by the upwardly sloping pockets 40 and 41'.

The block 42, shown in Figure 7, is similar to the block 34, shown in Figure 5, except that the wall 29 is deeper, the recessed part 27 eliminated and the notch 28 replaced by the upwardly slo ing pockets 40 and 41.

The block 43, own in Figure 8, is similar to theblock 21 shown inFiguie 4, except that the part 26- is done away with; otherwise it is exactly the same and bears the same nu- '47 and bottom surface 48 sloping u merals.

The intermediate block 44, shown in Figure 9 has a front surface 45 and a back sur face 46 paralleling each other, a top surface wardly and the notches 49 and 50, an en the blocks 39 and 42, are used the pocket 51, as shown by the dotted lines in Figure 9, is provided. y

In Figures 2 and 3, the structure shown comprises the buckstays 17, supporting on one side the brackets or angle supporting pieces 18 by the bolts 19 and nuts 20, the upwardly projecting angular end 52 of the bracket projecting into the groove 28 of the blocks 21 and 34, and the lowor right angled shelf 53 holding the blocks 21. and 34 upon the surface 26 and upon the top of the sloping surface 32, of these blocks r the blocks 44 are placed, these two types 21,

34 and 44 comprising the only shapes required to build up a wall 0 the wall ma be a built up without the use oft ese intern: 'ate blocks at all.

In Figure 10 the blocks 39 and 42, shown of bricks carried slopin pockets 40 and 41 engaging with upward oping angles 54 held to the buckstays 17 by the rivets or bolts 55.

The blocks preferably have the notches 30, 31, 35, 36, 49 and to provide for the expansion spaces'56, (see Fig. 3) to take care of the lateral e ansion of the wall, the vertical expansion bemg taken care of by the pockets 28 or 40 and 41,- depending upon the type of block utilized.

In Figure 12 one form of unit or segmental'wall-supporting element is shown illustrating the arts 52 and 53 and the holes 56', for boltmg to the I'beams 17 as illus-- trated in Figures 2 and 3. In Figure 13 another form of unit or segmental wall su porting element 57 is shown, wherein the ho tmg holes/56 are the same as shown in Figure 12 and the assembly of this form is shown in F' e 11 wherein the elements 57 are shown riveted to the I beams by the rivets 67.

the parts 27,28, 29, 32 and 33, are the same as corr 0nd parts of blocks previously describe this lock, however, having-no lateral notches or shoulders like those shownin Figures 4 to 9 inclusive.

In Figure 15 the alternate support'shown is comprised of a rod or pipe 68 which may be held to ,the buckstays 17 by means of the ofiset sup rt's 69 that are provided with bolt holes 70 or'bolting to the said buckstays.

' Havin thus'described and illustrated the preferre embodiment of my invention I do not wish to limit myself to the exact construction or arrangementof parts shown since it is evident that modifications may made therein without departing from the spirit of the invention or scope of the claims.
